The advertised detection accuracy of the company’s sensors is based on both external and internal testing, as outlined in each product’s specification document. Although our sensors are very accurate by industry standards, like all other sensor manufacturers we cannot guarantee perfection or assure that no errors will ever occur in any particular applications of our technology. Therefore, beyond the express Limited Warranty that accompanies each sensor sold by the company, we offer no additional representations, warranties, guarantees or remedies to our customers. It is recommended that purchasers and integrators evaluate the accuracy of each sensor to determine the acceptable margin of error for each application within their particular system(s).

Bid specifications

1.0 General. This item shall govern the purchase of aboveground radar presence detector (RPD) equivalent to the Wavetronix SmartSensor Matrix.

An RPD detects vehicles by transmitting electromagnetic radar signals through the air. The signals bounce off vehicles in their paths and part of the signal is returned to the RPD. The returned signals are then processed to determine traffic parameters.

RPDs are not affected by normal weather and environmental conditions such as rain, wind, dry snowfall, moist snowfall, dust, etc. They also do not require cleaning and can maintain performance over a wide range of ambient temperatures.

RPDs provide a non-intrusive means of detecting traffic. This property not only makes them safer to install but also more cost effective than sensors that require roadway modifications or placement.

2.0 Sensor outputs. The RPD shall present real-time presence data across a 140-ft. (42.7-m) range.

The RPD shall support a minimum of 16 zones.

The RPD shall support a minimum of 16 channels.

The RPD shall support user-selectable zone to channel mapping.

The RPD shall use AND logic to trigger channels when all selected zones are active.

The RPD shall use OR logic to combine multiple zones to a channel output, and shall have channel output extend and delay functionality.

The RPD algorithms shall mitigate detections from wrong way or cross traffic.

The RPD system shall have fail-safe mode capabilities for contact closure outputs if communication is lost.

3.0 Detectable area.

3.1 Detection range. The RPD shall be able to detect and report presence in lanes with boundaries as close as 6 ft. (1.8 m), measured laterally, from the RPD.

The RPD shall be able to detect and report presence in lanes located within the 140 ft. (42.7 m) arc, measured laterally, from the RPD.

3.2 Field of view. The RPD shall be able to detect and report presence for vehicles within a 90 degree field of view.

3.3 Lane configuration. The RPD shall be able to detect and report presence in up to 10 lanes.

The RPD shall be able to detect and report presence in curved lanes and areas with islands and medians.

4.0 System hardware. For each approach to be detected, one RPD corner radar shall be used.

4.1 Connectivity and surge. Each RPD shall be used with a preassembled backplate or a cabinet interface device.

If a traffic cabinet preassembled backplate, it shall have the following:

If a cabinet interface device, it shall be a single device that performs the following functions:

4.2 Contact closure input file cards. The RPD may use contact closure input file cards with 2 or 4 channel capabilities.

The contact closure input file cards for the RPD shall be compatible with industry standard detector racks.

5.0 Maintenance. The RPD shall not require cleaning or adjustment to maintain performance.

The RPD shall not rely on battery backup to store configuration information, thus eliminating any need for battery replacement.

Once the RPD is calibrated, it shall not require recalibration to maintain performance unless the roadway configuration changes.

The mean time between failures shall be 10 years, which is estimated based on manufacturing techniques.

6.0 Physical properties. The RPD shall not exceed 4.2 lbs. (1.9 kg) in weight.

The RPD shall not exceed 13.2 in. by 10.6 in. by 3.3 in. (33.5 cm x 26.9 cm x 8.4 cm) in its physical dimensions.

All external parts of the RPD shall be ultraviolet-resistant, corrosion-resistant, and protected from fungus growth and moisture deterioration.

6.1 Enclosure. The RPD shall be enclosed in a Lexan EXL polycarbonate.

The enclosure shall be classified “f1” outdoor weatherability in accordance with UL 746C.

The RPD shall be classified as watertight according to the NEMA 250 standard.

The RPD enclosure shall conform to test criteria set forth in the NEMA 250 standard for type 4X enclosures. Test results shall be pro-vided for each of the following type 4X criteria:

The RPD shall be able to withstand a drop of up to 5 ft. (1.5 m) without compromising its functional and structural integrity.

The RPD enclosure shall include a connector that meets the MIL-C-26482 specification. The MIL-C-26482 connector shall provide contacts for all data and power connections.

7.0 Electrical. The RPD shall consume less than 10 W.

The RPD shall operate with a DC input between 10 VDC and 28 VDC.

The RPD shall have onboard surge protection.

8.0 Communication ports. The RPD shall have two communication ports, and both ports shall communicate independently and simultaneously.

Two independent communication ports allow one port to be used for configuration, verification and traffic monitoring without interrupting communications on the dedicated data port.

The RPD shall support the upload of new firmware into the RPD’s non-volatile memory over either communication port.

The RPD shall support the user configuration of the following:

The communication ports shall support a 9600 bps baud rate.

9.0 Radar design. The RPD shall be designed with a matrix of 16 radars.

The matrix of 16 radars enables the sensor to provide detection over a large area and to discriminate lanes.

9.1 Frequency stability. The circuitry shall be void of any manual tuning elements that could lead to human error and degraded perfor-mance over time.

The RPD shall use frequency modulated continuous wave (FMCW) radar. All transmit modulated signals shall be generated by means of digital circuitry, such as a direct digital synthesizer, that is referenced to a frequency source that is at least 50 parts per million (ppm) stable over the specified temperature range, and ages less than 6 ppm per year. Any upconversion of a digitally generated modulated signal shall preserve the phase stability and frequency stability inherent in the digitally generated signal.

This specification ensures that, during operation, the RPD strictly conforms to FCC requirements and that the radar signal quality is maintained for precise algorithmic quality. Analog and microwave components within an RPD have characteristics that change with temperature variations and age. If the output transmit signal is not referenced to a stable frequency source, then the RPD is likely to experience unacceptable frequency variations which may cause it to transmit out of its FCC allocated band and thus will be non-compliant with FCC regulations.

The RPD shall not rely on temperature compensation circuitry to maintain transmit frequency stability.

Temperature-based compensation techniques have been shown to be insufficient to ensure transmit frequency stability. One reason this type of technique is not sufficient is that it does not compensate for frequency variations due to component aging.

The bandwidth of the transmit signal of the RPD shall not vary by more than 1% under all specified operating conditions and over the expected life of the RPD.

The bandwidth of an RPD directly affects the measured range of a vehicle. A change in bandwidth causes a direct error in the mea-sured range, i.e., a 5% change in bandwidth would cause a range error of 10 ft. (3 m) for a vehicle at 200 ft. (61 m). If the bandwidth changes by more than 1% due to seasonal temperature variations and component aging, then the RPD will need to be frequently reconfigured to maintain the specified accuracy.

9.2 Antenna design. The RPD antennas shall be designed on printed circuit boards.

Printed circuit board antennas eliminate the need for RF connectors and cabling that result in decreased reliability. Printed circuit antennas are less prone to physical damage due to their extremely low mass.

The vertical beam width of the RPD at the 6 dB points of the two-way pattern shall be 65 degrees or greater.

The antennas shall cover a 90 degree horizontal field of view.

The sidelobes in the RPD two-way antenna pattern shall be -40 dB or less.

Low sidelobes ensure that the performance from the antenna beam widths is fully achieved.

9.3 Resolution. The RPD shall transmit a signal with a bandwidth of at least 245 MHz.

The bandwidth of the transmit signal translates directly into radar resolution, which contributes directly to detection performance. For example, an RPD that transmits at a low bandwidth will have low radar resolution, which could cause it to count a single vehicle as two vehicles in adjacent lanes. As another example of the adverse effects of low radar resolution, the response from a sign or other radar target in the roadway may spill over into the lanes of travel and desensitize the radar. In order to achieve the specified detec-tion accuracy in a variety of conditions, the unwindowed radar resolution cannot be larger than 2 ft. (0.6 m) at the half-power level, which requires a bandwidth of 240 MHz. The high radar resolution reduces the problem of vehicle responses getting drowned out by brighter vehicles in adjacent lanes and improves performance for moving and stopped vehicles near roadway targets.

9.4 RF Channels. The RPD shall provide at least 8 RF channels so that multiple units can be mounted in the same vicinity without caus-ing interference between them.

9.5 Verification. The RPD shall have a self-test that is used to verify correct hardware functionality.

The RPD shall have a diagnostics mode to verify correct system functionality.

10.0 Configuration.

10.1 Auto-configuration. The RPD shall have a method for automatically defining traffic lanes, stop bars and zones without requiring user intervention. This auto-configuration process shall execute on a processor internal to the RPD and shall not require an external PC or other processor.

The auto-configuration process shall work under normal intersection operation and may require several cycles to complete.

10.2 Manual configuration. The auto-configuration method shall not prohibit the ability of the user to manually adjust the RPD configuration.

The RPD shall support the configuring of lanes, stop bars and detection zones in 1-ft. (0.3-m) increments.

When lanes have variable widths or have variable spacing (e.g. gore between lanes), precise resolution is necessary.

10.3 Windows-based software. The RPD shall include graphical user interface software that displays all configured lanes and the cur-rent traffic pattern using a graphical traffic representation.

A visual representation of traffic patterns allows an installer to quickly associate specific detections with corresponding vehicles, and it facilitates verification of RPD performance.

The RPD shall include the ability to do counting and pulse channels.

The graphical interface shall operate on Windows 7, Windows 8, and Windows 10 in the .NET framework.

The software shall support the following functionality:

11.0 Operating conditions. The RPD shall maintain accurate performance in all weather conditions, including rain, freezing rain, dry snow-fall, moist snowfall, wind, dust, fog and changes in temperature and light, including direct light on sensor at dawn and dusk. The RPD shall maintain accurate performance with ice and dry snow buildup on the sensor front.

RPD operation shall continue in rain up to 1 in. (2.5 cm) per hour.

The RPD shall be capable of continuous operation over an ambient temperature range of -40°F to 165.2°F (-40°C to 74°C).

The RPD shall be capable of continuous operation over a relative humidity range of 5% to 95% (non-condensing).

Dry snow and moist snow are terms defined by the International Hydrological Program of the United Nations in the publication “The Internation-al Classification For Seasonal Snow on the Ground.” Dry snow has a water volume content of 0% and moist snow has water content of less than 3%. Wet snow has higher fractional volumes of water and varying fractional volumes of air. Depending on the precipitation rate and the fraction-al volumes of ice, air, and water, the RPD shall be capable of continuous operation in wet snowfall. For example, with typical fractional volumes of ice, air, and water the RPD shall be capable of continuous operation in wet snowfall with a precipitation rate less than 1 in. per hour (2.5 cm) per hour. Furthermore, as instructed in the user documentation, the sensor should be installed with a down tilt for accurate detection. A down tilt alignment will also help shield the sensor front and minimize the possibility of dry, moist, and wet snow buildup in extreme weather conditions.

12.0 Testing.

12.1 FCC. Each RPD shall be certified by the Federal Communications Commission (FCC) under CFR 47, part 15, section 15.249 as an intentional radiator.

The FCC certification shall be displayed on an external label on each RPD according to the rules set forth by the FCC.

The RPD shall comply with FCC regulations under all specified operating conditions and over the expected life of the RPD.

The RPD shall be tested under IEC 61000-4-5 class 4 (lightning surge protection).

12.2 NEMA TS 2-2003 testing. The RPD shall comply with the applicable standards stated in the NEMA TS 2-2003 standard. Third-party test results shall be made available for each of the following tests:

13.0 Manufacturing. The RPD shall be manufactured and assembled in the USA.

The internal electronics of the RPD shall utilize automation for surface mount assembly, and shall comply with the requirements set forth in IPC-A-610C Class 2, Acceptability of Electronic Assemblies.

The RPD shall undergo a rigorous sequence of operational testing to ensure product functionality and reliability. Testing shall include the following:

Test results and all associated data for the above testing shall be provided for each purchased RPD by serial number, upon request.

14.0 Support. The RPD manufacturer shall provide both training and technical support services.

14.1 Training. The manufacturer-provided training shall be sufficient to fully train installers and operators in the installation, configura-tion, and use of the RPD to ensure accurate RPD performance.

The manufacturer-provided training shall consist of comprehensive classroom labs and hands-on, in-the-field, installation and configu-ration training.

Classroom lab training shall involve presentations outlining and defining the RPD, its functions, and the procedures for proper opera-tion. These presentations shall be followed by hands-on labs in which trainees shall practice using the equipment to calibrate and configure a virtual RPD. To facilitate the classroom presentation and hands-on labs, the manufacturer-provided training shall include the following items:

Field training shall provide each trainee with the hands-on opportunity to install and configure the RPD at roadside. Training shall be such that each trainee will mount and align the RPD correctly.

14.2 Technical assistance. Manufacturer-provided technical support shall be available according to contractual agreements, and a technical representative shall be available to assist with the physical installation, alignment, and auto-configuration of each supplied

RPD. Technical support shall be provided thereafter to assist with troubleshooting, maintenance, or replacement of RPDs should such services be required.

15.0 Documentation. RPD documentation shall include an instructional training guide and a comprehensive user guide as well as an in-staller quick-reference guide and a user quick-reference guide.

Certification documentation shall be available upon request.

16.0 Warranty. The RPD shall be warranted free from material and workmanship defects for a period of two years from date of shipment.

The advertised detection accuracy of the company’s sensors is based on both external and internal testing, as outlined in each product’s specification document. Although our sensors are very accurate by industry standards, like all other sensor manufacturers we cannot guarantee perfection or assure that no errors will ever occur in any particular applications of our technology. Therefore, beyond the express Limited Warranty that accompanies each sensor sold by the company, we offer no additional representations, warranties, guarantees or remedies to our customers.

The advertised detection accuracy of the company’s sensors is based on both external and internal testing, as outlined in each product’s specification document. Although our sensors are very accurate by industry standards, like all other sensor manufacturers we cannot guarantee perfection or assure that no errors will ever occur in any particular applications of our technology. Therefore, beyond the express Limited Warranty that accompanies each sensor sold by the company, we offer no additional representations, warranties, guarantees or remedies to our customers. It is recommended that purchasers and integrators evaluate the accuracy of each sensor to determine the acceptable margin of error for each application within their particular system(s).

1.0 General. This item shall govern the purchase of aboveground continuous tracking advance detector (CTAD) equivalent to the Wavetronix SmartSensor Advance.

A CTAD detects vehicles by transmitting electromagnetic radar signals through the air. The signals bounce off vehicles in their paths and part of the signal is returned to the CTAD.

The returned signals are then processed to determine traffic parameters. CTADs are not affected by normal weather and environmental conditions such as rain, wind, dry snowfall, moist snowfall, dust, etc. They also do not require cleaning and can maintain performance over a wide range of ambient temperatures.

CTADs provide a non-intrusive means of detecting traffic because they can be installed at the side of a roadway. This property not only makes them safer to install but also more cost-effective than sensors that require roadway modifications or placement.

2.0 Measured quantities and outputs. The CTAD shall detect range and speed to the stop bar for vehicles or clusters of vehicles moving in the user-selected direction of travel. The CTAD shall dynamically track and update the estimated time of arrival (ETA) for each vehicle as it approaches the stop-bar; each newly-measured ETA result will be continually compared against the pre-determined ETA ranges that define the dilemma zone, and a green light extension request will be provided to the controller when one or more vehicles are within that range.

The CTAD shall also detect instantaneous roadway efficiency.

Dynamic ETA tracking allows the sensor to adjust the ETA over time when approaching vehicles accelerate or decelerate. This allows the ETA-based zone detections to be more accurate than single ETA figures based on spot-speeds from a single location.

The CTAD shall be able to simultaneously detect and report information from up to 25 vehicles on the roadway when they are serially se-quenced between the near and far boundaries.

The CTAD shall turn on a zone output when the range, speed, ETA, and qualified count or instantaneous roadway efficiency requirements for that zone are satisfied.

The CTAD shall turn on an alert output on when the userdefined zone output combinational logical is satisfied.

The CTAD shall turn on a normal channel output when any of the channel’s alerts is on and the channel’s delay and extend time constraints are satisfied.

The CTAD shall turn on a latched channel output when the on alert is turned on and the delay time is satisfied. The CTAD shall turn off a latched channel output when the off alert is turned on or the max timer expires and the extension time is satisfied.

Channel outputs are used to create contact closures which can be used as inputs into a traffic controller.

The CTAD shall provide vehicle call and extend data on up to eight channels that can be connected to contact closure modules compliant with NEMA TS 1, NEMA TS 2, 170, and 2070 controller cabinets.

The CTAD shall be capable of providing data for each tracked detection over the serial ports.

The CTAD shall have Pulse channel outputs for intersection arrival-time information.

When vehicular track file data is available on the serial ports, the data is then available on the communications network without the use of a traffic controller or a contact closure data recorder. Vehicular track file data is useful for traffic study applications and for performing comparisons between traffic sensors.

3.0 Detectable area.

3.1 Mounting location. The CTAD shall be able to detect and report vehicle information when mounted within 50 ft. (15.2 m) of the center of the lanes of interest.

The CTAD shall be able to detect and report vehicle information when mounted at heights up to 40 ft. (12.2 m) above the road surface.

3.2 Detection range. The CTAD shall be able to detect and report information on the roadway located with the near boundary at 50 ft.

(15.2 m), measured laterally, from the CTAD.

The CTAD shall be able to detect and report information on the roadway located with the far boundary at 600 ft. (182.8 m), measured laterally, from the CTAD.

For incoming traffic, 95 percent of large vehicles within the line-of-site of the CTAD shall be detected and reported before they arrive 400 ft. (121.9 m) from the sensor. For incoming traffic, 90 percent of all motor vehicles within the line-of-site of the CTAD shall be de-tected and reported before they arrive 400 ft. (121.9 m) from the sensor.

4.0 Performance.

4.1 Detection accuracy. The CTAD shall detect at least 98 percent of large vehicles like truck-trailer combinations and at least 95 per-cent of all motor vehicles within the line-of-sight of the CTAD sensor where multiple detections of multi-unit vehicles are not considered false detections and merged detections of adjacent lane vehicles are not considered missed detections.

4.2 Range accuracy. The CTAD shall provide range measurements in which 90% of the measurements are accurate within 10 ft. (3 m) when the vehicle is tracked independently.

4.3 Speed accuracy. The CTAD shall provide per vehicle speed measurements in which 90% of the measurements are accurate within 5 mph (8 kph) when tracked independently.

4.4 ETA accuracy. The CTAD shall provide estimated time-of-arrival (ETA) measurements in which 85% of the measurements are ac-curate within one second, when the detected vehicles are tracked independently at a constant speed above 40 mph (64 kph) and are within 2.5 and 5.5 seconds of the stop bar.

5.0 Performance maintenance. The CTAD shall not require cleaning or adjustment to maintain performance.

The CTAD shall not rely on battery backup to store configuration information, thus eliminating any need for battery replacement.

Once the CTAD is calibrated, it shall not require recalibration to maintain performance unless the roadway configuration changes.

The mean time between failures shall be 10 years, which is estimated based on manufacturing techniques.

6.0 Physical properties. The CTAD shall not exceed 4 lbs. (1.8 kg) in weight.

The CTAD shall not exceed 14 in. × 11 in. × 4 in. (35.6 cm x 27.9 cm x 10.2 cm) in its physical dimensions.

All external parts of the CTAD shall be ultraviolet-resistant, corrosion-resistant, and protected from fungus growth and moisture deterioration.

6.1 Enclosure. The CTAD shall be enclosed in a Lexan polycarbonate.

The enclosure shall be classified “f1” outdoor weatherability in accordance with UL 746C.

The CTAD shall be classified as watertight according to the NEMA 250 standard.

The CTAD enclosure shall conform to test criteria set forth in the NEMA 250 standard for type 4X enclosures.
